Worked on the odoo/documentation repository to update installation guides for Odoo 19, focusing on raising the minimum required PostgreSQL version from 12.0 to 13.0. This documentation change was implemented using reStructuredText (RST) and emphasized cross-platform compatibility by ensuring instructions were consistent across Linux, Windows, and macOS environments. The update aligned Odoo’s on-premise installation requirements with current PostgreSQL security standards and feature sets, reducing potential support issues. The work demonstrated attention to documentation best practices, with clear, platform-specific guidance that improves maintainability and user experience. No bugs were fixed during this period, with efforts concentrated on documentation quality.
